in the vietnamese capital of hanoi, vo trong nghia architects has renovated a city center property that has stood on the site for 15 years. the design is a direct response to the country’s fast rate of development, a growth that has seen green space marginalized and the subsequent rise of environmental problems such as air pollution and flooding.

the dwelling is defined by its green façade, a cascading waterfall of vegetation that provides pleasant external views, while simultaneously ensuring privacy. old security fences have been removed, and replaced with galvanized steel trellises, attached to existing balconies upon which climbers grow. the façade is not only for residents, but also for neighbors, presenting an attractive leafy elevation to its surroundings. together with a roof garden that sits at the top of the property, the vegetation reduces energy consumption – shielding the building from harsh western sunlight.

internally, the previously existing concrete staircase has been replaced with slender steel stairs, bringing natural light and ventilation inside the structure. in order to encourage communication between residents at ground and first floor levels, a void has been inserted – connecting the dining space with the study. protecting against damp and condensation, the property’s ground floor has been raised to install air ventilation.

the environmental system is imagined as a prototype that can be applied to other structures in tropical climates, offering solutions to serious urban problems where the benefits of a green home can have a wider positive impact on the city.
